This is my third period. The first two were very light and non frequent. This one is very heavy. I have light panty liners and it soaks in about 30 minutes. I have to put 3 or 4 in my panties so my underwear doesn't stain. When I tried using a tampon, I fainted. I have tried tampons more but I can feel it when I sit and I get hot and light headed when I put it in. I'm scared to go to school because I'm scared the blood will soak through my pants. Can anyone help me?
